We describe a family of proteins which regulate transcription of inducible genes in bacteria (GalR-LacI family). An alignment of the proteins in the GalR-LacI family is presented in which these proteins show a very high degree of similarity (60%) throughout the entire sequences. The homology is greatest among the amino-terminal DNA binding domains. Since a portion of the operator sequences occupied by these proteins is also conserved, a similar DNA structure may be required for specific recognition of DNA by members of the GalR-LacI family. Highly conserved motifs involved in effector binding and oligomerization are also identified. This compilation suggests a widespread conservation of these regulators among bacteria, and have strong implications for further study of peptide motifs in domain function, as well as pathways of protein evolution.
